Background
In 2014, beilang, germany, introduced a PICC catheter with electrocardiographic guidance, "schuttop". So far, the method has been used for more than 5 years, but the method is not widely used. The main reasons are two: 1. a certain electrocardiogram knowledge is required for the operator. 2. The theoretical basis is insufficient: the brown company considers that the height of the P wave is consistent with that of the QRS wave when the electrode is at the sinus node, but the electrocardiogram is a projection of an electrocardiographic vector on a certain axis, which means that the magnitude of a projection of a comprehensive vector of the P wave (frontal plane pointing to the lower left front) and a comprehensive vector of the QRS wave (frontal plane pointing to the lower left) on the II lead are consistent. However, after practical operation, the intracavitary electrocardiogram performance of most patients is not the same.
European countries are studying 3D navigation, which is based on three-dimensional reconstruction of thoracic CT, and then place the patient in a magnetic field, and guide the catheter into position by comparing the trajectory change of the magnetic probe in the magnetic field with the three-dimensional data in the computer.
